Just got this 2007 sportsman 800. The previous owner said the drive belt needed replacement and provided me with an aftermarket belt can't find sleeve but i think the brand started with a V. I checked the part # on line and it was correct. So old belt was totally smoked. Installed new belt and now at idle the machine is moving forward and very hard to shift. This belt seamed very tight on pulleys / clutch so there is no slippage at idle. Should I go with an OE belt?
